British animal rights activist Barry Horne is serving a lengthy prison sentence for arson attacks against people and places he considers cruel to animals. Mr. Horne has ended a 67-day hunger strike protest after British government officials promised to look into the use of animals in experiments. In recent years, groups like Britain’s Animal Liberation Front has claimed responsibility for dozens of guerrilla-style attacks, and had threatened to assassinate 10 people it accused of cruelty to animals if Mr. Horne had died on hunger strike. Steve Curwood speaks with journalist Kevin Toolis who has covered Britain’s animal rights movement for the Guardian newspaper.
